No matter which type of cutting equipment cuts the product, there will be errors, it's just that the cutting error varies greatly. The error of the wall cutting machine can be controlled manually. It is recommended to achieve one-time cutting as much as possible during cutting, and avoid repeated cutting as much as possible.

There are four main reasons that affect the quality of wall cutting and cause size:

1. If the flatness of the board is not good, it will cause changes in size after cutting;

2. When cutting long and wide strip parts, common edge cutting can be used. First, cut the long side, and then cut the short end when it cools down.

3. Due to the slow cutting speed of the wall cutting machine, it takes a long time to preheat, which can absorb too much heat and easily cause thermal deformation

4. During the entire cutting process, the material will be released locally as it is removed, which can easily cause deformation and result in a decrease in cutting size.
